A throwback to 2011 and a video of Canadians Joshua Lavigne and Raphael Slawinski on the first ascent of Tsunami M5 WI5+ in 2011, a 300-metre long mixed route on Mount Patterson in the Canadian Rockies.

Slawinski and Lavigne have dozens of high-quality new routes to their names over the years. Tsunami hasn’t formed much and is likely unrepeated, but you never know.
